Abstract
The present invention discloses a production process of blank for making solid wrench and double offiset ring spanner, and said process includes the main following steps: heating raw material rod, die stamping to obtain forming blank, then directly-adopting red-stamping forming techinque i.e, directly-stamping "U"-shaped working slotted eyes of two ends of solid wrench and ring-shaped working through holes of two ends of double offiset ring spanner, having no working allowance, then cutting off overlap so as to obtain the invented required blank body.
Description
Technical field
The present invention relates to the processing technology of fork spanner and double offset ring spanner base substrate.
Background technology
Fork spanner and double offset ring spanner are the common hardware ﹠ tools of using always, the two ends of fork spanner and double offset ring spanner are respectively arranged with work slotted eye and work through hole, that is: the two ends of fork spanner are respectively arranged with different openings size " U " shape slotted eye, in order to tighten or to unclamp corresponding specifications of nuts or bolt etc.; The two ends of double offset ring spanner are respectively arranged with the plum blossom shape through hole in different apertures, equally in order to tighten or to unclamp corresponding specifications of nuts or bolt etc.Since fork spanner and double offset ring spanner appearance, the processing technology of their base substrates is basic identical, as shown in Figure 1, is mainly: at first fuel rod is heated; Die-forging forming base then, promptly die forging becomes fork spanner shape base and double offset ring spanner shape base respectively; Cut overlap again, then after the annealing cooling; The cold punching working hole that is: goes out " U " shape opening slotted eye at the two ends of fork spanner cold punching, and at the flower-shaped after the rainy season through hole of the two ends of double offset ring spanner cold punching; Because it is higher to the required precision of fork spanner and double offset ring spanner two ends working hole, its aperture is excessive or too smallly all can not normally use, promptly can not be used for tightening or unclamping nut etc., thereby behind the cold punching working hole, also must carry out milling or broaching processing, to guarantee the machining accuracy of working hole to working hole; Behind milling or broaching working hole, just made required base substrate.The shortcoming of above-mentioned processing technology is: at the die-forging forming base, cut overlap after, also need just can be processed into required base substrate through annealing, cold punching working hole and milling or this three process of broaching working hole, and need be equipped with special-purpose annealing device, milling or broaching equipment and cutter, this has not only increased production cost, and technology is complicated, and required time of operation is also longer; Because factory produces in enormous quantities, the production process time one of base substrate is elongated, and will reduce production efficiency greatly.
Summary of the invention
At the problems referred to above, the present invention will provide a kind of technology is simple, production efficiency the is higher fork spanner and the processing technology of double offset ring spanner base substrate.
The technical solution used in the present invention is: the processing technology of described fork spanner and double offset ring spanner base substrate mainly comprises: at first with fuel rod heating, die-forging forming base then; Behind the die-forging forming base, directly adopt the red type technology that is washed into, promptly directly red " U " shape work slotted eye at fork spanner two ends and the plum blossom shape work through hole at double offset ring spanner two ends gone out do not stay allowance, and then cuts overlap, just made required base substrate.
Advantage of the present invention is: one, shortened the required time of a whole set of technology, particularly for production in enormous quantities, improved production efficiency greatly; Two, reduced working strength of workers; Three, because the red type of being washed into can directly guarantee the machining accuracy of working hole, need not reprocess, thereby save special annealing device, milling or broaching equipment and the cutter that is equipped with of original need, reduce production cost.
Description of drawings
Fig. 1 is the processing process figure of described fork spanner of prior art and double offset ring spanner base substrate;
Fig. 2 is the processing process figure of fork spanner of the present invention and double offset ring spanner base substrate.
Embodiment
As shown in Figure 2, the processing technology of fork spanner of the present invention and double offset ring spanner base substrate mainly comprises: at first with fuel rod heating, die-forging forming base then; Behind the die-forging forming base, directly adopt the red type technology that is washed into, promptly directly red " U " shape work slotted eye at fork spanner two ends and the plum blossom shape work through hole at double offset ring spanner two ends gone out do not stay allowance, and then cuts overlap, just made required base substrate.Process chart shown in Figure 2 is compared with process chart shown in Figure 1, annealing, cold punching working hole and milling or this three process of broaching working hole have been saved, like this, reduced when producing in enormous quantities carrying back and forth number of times, reduced working strength of workers and landed cost in the blank of material of ton; Save special annealing device, milling or broaching equipment and the cutter that is equipped with of original need, greatly reduced production cost, improved production efficiency.
